Nowadays, most open-pit excavations around the world after the exploitation are flooded with water and artificial lakes are created.The creation of lakes is now the most common use of post exploitation voids. These lakes are mainly used for recreational purposes.This thesis aims to study the effect of the water level changes on the stability of the slopes. Lake Most (Czech Republic) constitutes the field of this investigation. This effect is studied through fully coupled flow-deformation analyses.The analyses have taken into account the Van Genuchten hydraulic model that expresses the soil's ability to retain water mainly in the vandose zone and is combined with the elastic-plastic models of soil materials. The geotechnical parameters of the geomaterials were determined by laboratory and field tests and the kinetic behavior of the slopes of the lake was simulated using the Plaxis 2D V16 finite element software.The simulation results showed that the stability of the slopes depends on the magnitude of the water level variation, the permeability of the soil formations and the rate of the water level change of the lake. The results of the work can be applied in other sites, and they can be used for the optimal design of filling and operation of the pit lakes.
